Mounted on the side bars h2 of thel 'frame l1.,l and between the frame and the furnace a. are. other slides i1 through which the supplemental side hars i are movable. and in the bottom portions of the slides 7 is mounted similar mold j whichis secured to the cross head o and the.

a transverse shaft 1j provided at one end with an arm jl' by which it may be rotated. 'l'he shaft j is provided between the b ai's i w-itli arms j which are rigidly secured thereto and with which are connected links A.jt and the links j' are pivoted to a. cross head j provided at its ends with keepers which are movable ou the` side bars 71.2 and i and through which the side bars 2' are movable. lhe slides if are connected with the slides F `by-.screws and said screws,

and the front end of said frame rests on I the slides 'lhe yoke-shaped frame 1 is shown detached in Fig. -lland preferablyI consists of top and bottoni members and?,

' separated 'by blocks as shown at la? or in any desired manner, and the transverse part of said traine is provided ou the bottom thereof with a' keeper Z13 through which is passed a movable plate. to the front end of which is secured a block m. 'Phe block 111/ i consists of a verticali-y arranged rear meniber m2 and forwardly directed arms m3, m4 and 121,5, and the plate li' is secured between f the arms m* and arr of said block, and a transverse lever-0i is pivoted in one side, of the yoke-shaped frame Z1 at n. and passes transversely across the frame l1. and between the top and bottom parts ff" and la of the yoke-shaped `frame 7a2 and spivoted between tlie arms .fr/H and m," of the block 'nr by means of a pin which passes through a longitudinal slot. formed therein as shownl at n3: and a supplemental block n. is secured to the bottom of the block n1` and by means thereof a cut-ott'I plunger m5 is rotatably secured to the block mat and in the manner shown at in in Figs. 1,2, 5l and 4.

;\ crcss head o is sceuredt'o t-heirear ends of the. supplemental side bars 'i and two aws y) are provided, one of other to'the cross head f'. this connection benglpreferably iliade by screws as shown at )f2 and said `mold jaws 7) and the cross heads j and o are provided with a central transverse passage p3. and when these'parts arc in the position shown-in Figsfl and the passage j through the mold jaws /f and cross heads j and 0 communicate withthe i nozzle Z7 of the discharge f7 ot the. supple- *j mental meltingpot 7, and the cut-ott' plun-v ger m7 operates through the passage 7; and through the cross heads j and o and mold jaws p as hereinafter described The mold jaws p are provided in their adjacent facesv` 'shown in Figs. 1 and with casting chambers r, one'half of said chambers being in one mold jaw and the other half in the other mold jaw and these chambers which, as shown in the drawing, are spool-shaped in form are placed in communication with the passage p' b y small radial passages r2 as clearly shown in Figs. l, Q and 3. L17 4 An annular water jacket 02 is mouiited on the nozzle d? of the discharge (Z3 of the supplemental melting pot (I. and this water jacketis provided with tubular connections o which serve as inlets and outlets for water. and in practice cr in the use of the machine as hereinafter described water may be constantly circulated through the water jacket o2 in order to cool the nozzle (ZT and the adjacent parts.

The cross head i5 with a hub s in the shown, and through plunger m7 operates. In practice, the ,water jacket of may bc made detachable or it may be secured in position in any desired manner, or it may be secured to the cross head o, and thus be made removable from the nozzle (ZT when said cross head is moved forwardly, this operation being performed. when desired by turning the shaft 2'.

From the foregoing description it will be seen by moving the arm i2 of the shaft z' forwardly the slides 5 and if aud the supplemental `side bars i" connected with said slides. together with the cross head o, the shaft 7' and cross head j5 together with the mold jaws j), the yoke-shaped frame k2. andthe parts mand n by which the plunger cut-oft' m7 is operated may all be moved forwardly,

is provided centrally form of construction whlch the cut-off :and this will separate the cross head o and the mold jaw p connected therewith from the nozzle (Z7, and if the. water jacket 02 be connected with the cross head o it will be separated from said nozzle, but in the ordinary operation ofthe machine the above parts are moved, the cross head o with its moldl jaw p remaining stationary or in the position shown in Figs. l, 2 and It4 will also be seen that with the parts in the position y 3, the shaft j may be rotated by turning the arm jg forwardly so as to move the slides j together with the cross head jf', and the mold jaw p ctmnected therewith into the position shown in Fig. 2 so as to separate the mold jaws p. and with the parts in the position shown in Figs. l. and 3 the arm 1" may be operated so as t-o move the cut-off plunger-m7 into the position shown in either of said figures.

This machine is particularly designed for casting various articles from what are known as soft or comparatively soft metal which will melt quicker than steel or cast iron. and

in practice the metal or metals to be molded and from which the castings are to be made are placed in the main melting pot cv and the bottom of the burner is ignited. The molten metal, as 'will be, understood passes into the cylinder d2 through the opening g and fills the supplemental pot (l, and said cylinder and the discharge, or discharge tube d, up to the opening g. At this stage of the procedure the cross head 0 andmold jaw 7; connected therewith being in the position shown in Figs. 1, 2 and 3, the cross head j and mold jaw y; are also moved in the positiou'shown in said figures by means of the arm jg, and there is a continuous passage 'from the discharge 1? of the pot f into the casting chamber or chambers r. The piston f/ is then. forced downwardly by means of the arm j' and the pressure of said piston on the molten metal in the pot- (l forces said metal up through the discharge (Z3 and through the nozzle (i7, and into the casting chambers 1' in the jaws y), andthe said molten metal fills said chambers. The lever n, is then moved backwardly and the cut-olf plunger 'm7 is forced backwardly through the lnold jaws y), and into and through the nozzle ([7, and all surplusmolten metal is cut ofl' and forced back through said parts,

and into the discharge Z3 of the pot (I a-nd flows downwardly into said pot and this keeps all the molten metal in proper condi` tion for a re-operation of the plunger y/ and the making of new castmgs. At the end of the above described operation the arm j2 of tlie shaft j is moved forwardly and the cross head f5 and its mold jaw 11 are moved into the position shown in Fig. 2, and the castings dropout of the casting chambers 'r and fall into a suitable receptacle provided therefor, and this operation may be continued as longas desired or unt-il it becomes necessary to again ll the main melting pot with metal.

It will be observed that the supplemental pot is, entirely within the main pot n as is also the discharge tube or passage' d, and with this construction the molten metal in said parts is kept in proper condition for casting at all times and by reason of theop- `eration of the cut-otf plunger mi as herein shown and described. all surplusage of metal at each casting operation is forced into the said discharge i and flows back down into the pot r/ and mingles with the body of molten metal therein.

ln Fig. 7 l have shown a modified form of the cross head o and a modified Ineans for connecting it with the side bars 'i0 in which :aid cross head, instead of being rectangular in form, as shown in Fig. comprises a central body portion having projecting arms 05 provided at their ends with yoke-shaped keepers t and in which the bars i are secured by means of screws 06 and the bars 112 also pass through said keepers.

Although I have shown and described the cross heads 0 and 7'5, and the mold jaws ny as .formed separately and connected it will be apparent vthat this method of connecting said parts isnot absolutely essential, and said parts may be formed integrally if desired; and although l have shown and described the main melting pot c and supplemental pot (Z as formed separately it Wl also be apparent that this method of nstrueting said parts is not absolutely essential and said parts may be formed integrally if desired. The casting chambers r in the mold jaws y) may also be made of an)7 desired shape or form according to the design or configuration of the. articles to be Cast, and any desired number of said casting chambers may he employed as will be readily understood.

The side of the yoke-shaped frame k2 to which the lever n is pivoted as shown at n2 is provided with a plurality of apertures t2 whereby the pivotal point of said lever may be adjusted forwardly or backwardly as may be desired so as to regulate the operation of the plunger cnt.-otl` m. lt will also beunderstood thatthe adjustment of the shafts z' and 7 forwardly and baekwardly on the frame h facilitates the operation of the apparatus and the movement of the cross heads 0 and j may be regulated as may be desired. f

My invention is also not limited to the -particular means herein shown and described for supporting the cross head 0 and its m ol dj aw y), and t. se parts may be supported in connection wi .he nozzle (ZT in any desired manner and l prefer to support thc said cross head and its mold jaw 7i in connection with the nozzle (il so that said parts can be moved toward and from said nozzle.

rThe construction of the furnace as herein shown and `described is not claimed herein but is claimed in the prior application hereinbefore referred to.

lla ving fully described my invention,what l claim as new anddesire to secure by Letters4 Patent, is

1. ln a casting machine, of the class described. a lnrnace.provided with a projecting discharge nozzle, ay frame in front. of said nozzle, shafts vmounted transversely of said frame and adjustable toward and from the furnace. mold jaws supported in front of said nozzle, and movable toward andfrom the same, devices connecting said mold jaws with said shafts, a eut-ofl` plunger movable provided with a central passage adapted to register with said nozzle; devices mounted in said frame for holding said mold jaw in connection with said nozzle and in contact wit-h said water jacket and whereby said mold jaw may be moved toward and from said nozzle, another mold jaw movable to- 'ard and from the first named mold jaw and provided with a: central passage corresponding with the central passage in first named mold jaw; devices mounted in said frame and in operative connection with the last named mold jaw for moving said jaw forwardlv and backward] f' and' for holding the same in connection with the first named mold jaw, said mold jaws being provided in their adjacent faces with mold chambers in connection with the passages therein. a plunger movable forwardly and l'mekwardlj.7 through the central l'iassages in said` mold jaws when the latter are in their operative position and into said nozzle and means for operating said plunger.
